The rule amongst honorable men of certain western cultures (
New England Boarding Schools) which states that a human and his or her partner must go out on exactly three dates before being formally considered a couple. If the possible couple-to-be has
gone out on three dates, still unsure of if they wish to be formally considered a couple or not, the 3rd
Date Rule dictates that the pair must make their decision then. Finally, the 3rd
date rule states that an honorable person does not ask the same partner on three dates in a row without intention to belong to them and them alone or can otherwise be considered to be “leading them on.”
